Argon Nitrogen Mixture For Welding — stable arcs and sound welds
An argon nitrogen mixture for welding from REAL GAZ gives the welder an inert shield with a small nitrogen share that helps preserve nitrogen in duplex welds and can improve arc behaviour on some stainless steels.
Adjusting the nitrogen fraction changes penetration and bead profile, so the correct mixture should be chosen with the filler and the procedure.
Adjusting the nitrogen fraction changes penetration and bead profile, so the correct mixture should be chosen with the filler and the procedure.
Compositions are consistent with EN ISO 14175, and the procedure side aligns with EN ISO 15609-1, supporting industrial workshops and laboratory weld testing.
🏭 Where Argon–Nitrogen Welding Mixtures Are Used
- ⚙️ TIG welding of duplex steel — nitrogen additions help keep the ferrite–austenite balance;
- 🛢️ Subsea and offshore parts — corrosion-resistant welds are required in marine service;
- 🥛 Food and beverage tanks — stainless welds must be smooth and clean;
- 🔧 Backing and purging — nitrogen-bearing backing gas protects the pipe root.
💡 Why Choose REAL GAZ
- ✅ Weld quality — a controlled shield reduces discoloration and defects;
- 🧪 Dry gas — moisture is limited to protect against porosity;
- 🎯 Procedure alignment — the label supports weld records;
- 🔒 Consistent flow — regulated supply keeps the pool protected;
- 📄 Certificate of Analysis (CoA) — supplied with every order.
🔬 Quality Control & Safety
- moisture and oxygen check;
- blend verification;
- regulator thread and valve check;
- leak testing.
Cylinders comply with ADR / UN transport rules and relevant EN/ISO standards.
📦 Grades, Cylinders & Handling
- 📌 Torch gas — set flow rates for torch size and nozzle diameter;
- 📌 Draughts — shield the weld area from wind outdoors;
- 📌 Equipment — use a flowmeter regulator rated for mixed gases;
- 📌 Tests — use test coupons before starting production welds.
🧭 Setting Up the Welding Station
Good results depend on the gas reaching the pool without picking up air on the way. Use a regulator with a flowmeter, short lengths of dry hose, and a gas lens or correctly sized nozzle on TIG torches. Typical flow rates fall in the range of a dozen litres per minute, but follow the torch manufacturer's guidance and adjust for draughts. Pre-flow and post-flow settings protect the electrode and the cooling weld. When welding pipes, seal the ends and purge the bore until the oxygen reading is low before the root pass. A short test weld with the new cylinder confirms that the setting suits the joint. Keep a log of flow settings and cylinder batches next to the weld records, so repeat jobs start from proven parameters. Welders new to nitrogen-bearing shield gas often notice a slightly different arc sound and pool fluidity; a few practice beads on scrap help adjust technique quickly.
